Just when you thought it was done..........All NAD's are not created equal and there is more to consider then just rated power, what amp are you looking at? Amps as in overall current would be the first thing I look at. If your integrated is doing 25 and the other amp you are looking at is doing 45 or 50 you may want to take a closer look. The wattage may be irrelevant to some but there is more to consider then just watts. What kind of volume do you like to listen to your music at?
